ISS Daily Summary Report – 4/18/2017
JEM (Japanese Experiment Module) Airlock (JEMAL) Operations:   They replaced the Multi-Purpose Experiment Platform (MPEP) on the Slide Table (ST) with the Cyclops to support the EVA contingency tie-down during NREP transfer to and from the ST via the JEM Remote Manipulator System (JEMRMS). 

Is someone able to explain this with plain words for a non-English native speaker?

ISS has two main release mechanisms available to deploy payloads from the JEM airlock. Usually, the standard small satellites are released from their containers, which are held by the MPEP, but non-standard payloads use the Cyclops (SSYKLOPS). This MPEP/Cyclops+containers+satellites is brought outside on the Slide Table in the airlock, and maneuvered with the JEM robotic arm to the "launch" position. Once the satellites are away, the container+MPEP/Cyclops is cycled back inside through the Slide Table and airlock.

The NREP is a payload installed in the JEM-EF (exposed facility, the "porch" of ISS) since August. I am not entirely sure why, but it looks this facility is being brought inside - I imagine because of OA-7's arrival with some experiments that need to be loaded up in NREP for exposure. Cyclops is able to have it tied down by EVAers in the case of a contingency prevents NREP from having it secured to either the slide table in the airlock or the JEM-EF's facility attachment points, and apparently MPEP doesn't offer the same capability.

Thank you for your detailed answer.
It is the first time that I heard about a contigency EVA in connection with installation/deinstallation on the JEM-EF.

ISS Daily Summary Report – 4/19/2017

Posted on April 19, 2017 at 4:00 pm by HQ.
 

Fluid Shifts Dilution Measurements:  The 49S subjects continued their Return minus 45 (R-45) Fluid Shifts Dilution Measurements activities today, collecting saliva, blood and urine and inserting them into Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) prior to ingesting a Sodium Bromide (NaBr) tracer. Throughout the day, the crew will perform more collections, storing them in MELFI as well.  Fluid Shifts is a joint NASA-Russian experiment divided into Dilution Measurements, Baseline Imaging, and Baseline Imaging with Chibis (Lower Body Negative Pressure). The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut’s eyes.  Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and to prevention of eye damage.

European Space Agency (ESA) Active Dosimeter Swap:  The crew replaced an Active Dosimeter Mobile Unit and downloaded the recorded data to an Active Dosimeter Personal Stowage Device. The European Crew Personal Active Dosimeter is worn by European ISS crewmembers on orbit to measure radiation exposure. This device, coupled with other dosimeters in the Columbus Laboratory, provides radiation dosage information that can be used to support risk assessment and dose management. The goal is to enable the verification of radiation monitoring systems for future medical monitoring of crewmembers in space.

Japanese Experiment Module (JEM) Airlock (JEMAL) Operations:  The crew depressed the airlock and vented remaining air in preparation for NanoRacks External Platform (NREP) operations next week.

Dose Tracker: The crew completed a medication tracking entry in the Dose Tracker application that runs on an iPad. Dose Tracker documents the medication usage of crewmembers before and during their missions by capturing data regarding medication use during spaceflight, including side effect qualities, frequencies and severities. The investigation is expected to provide anecdotal evidence of medication effectiveness during flight and any unusual side effects experienced. It is also expected that specific, near-real-time questioning about symptom relief and side effects will provide the data required to establish whether spaceflight-associated alterations in pharmacokinetics or pharmacodynamics is occurring during missions.

Mobile Serving System (MSS) Operations:  Yesterday afternoon, Robotics Ground Controllers maneuvered the Space Station Remote Manipulator System (SSRMS) into position for the start of the Orbital ATK-7 (OA-7) Offset Grapples Practice Session. They then powered up the MSS in the Hot Backup configuration for the crew to practice maneuvering the SSRMS into the grapple envelope of the Permanent Multipurpose Module (PMM) Flight Releasable Grapple Fixture (FRGF). They performed this several times and then performed a final run during which Ground Controllers safed the SSRMS to simulate a failure. The crew recovered by switching from the Cupola Robotic Workstation (RWS) to the Lab RWS and backing the SSRMS away. After the Offset Grapples Practice session, Ground Controllers reconfigured the MSS for nominal operations and maneuvered the SSRMS to a park position.  Finally, Robotic Flight Controllers performed a Direct Drive test of the Wrist Roll Joint (1) for mechanism health trending. Data collected will be compared with the data collected for joint 7.

On-Board Training (OBT) Robotic Onboard Trainer (RoBOT): Following yesterday’s successful launch of OA-7 and planned capture/berthing this Saturday, the crew completed a training session utilizing the RoBOT. They performed three Capture Point hold runs and numerous two meter runs. They also completed a self-study session.

ISS Daily Summary Report – 4/20/2017

Posted on April 20, 2017 at 4:00 pm by HQ.
 

50 Soyuz (50S) Launch/Dock: 50S launched from the Baikonur Cosmodrome today at 2:13AM CDT with Fyodor Yurchikhin and Jack Fischer aboard and docked in the automated mode to the Mini Research Module (MRM)-2 at 8:24AM CDT.  Following hatch opening at 10:05AM CDT, all crew members participated in a crew safety briefing to review emergency actions and roles and responsibilities in the event of a depressurization, fire or toxic release. With the arrival of these crewmembers the ISS is in 5-crew operations.

Electromagnetic Levitation (EML) Sample Coupling Electronic (SCE) Changeout: The crew swapped SCE Chambers in the Experiment Module of the EML today.  The SCE measures electrical resistivity of samples inside the EML which contains 4 inserts for Electromagnetic Levitation samples. The experiment samples are installed in a dedicated Sample Chamber that is attached to EML and will be replaced by new Sample Chambers for new experiment batches.

Microgravity Experiment Research Locker / INcubator (MERLIN) 2 Health and Status Troubleshooting:  The crew performed troubleshooting steps to recover Health and Status data which terminated on March 30, 2017. The crew then attempted to reboot the computer but the unit failed to reboot and is no longer cooling. A replacement MERLIN will arrive on OA-7.

Orbital 7 (OA-7) Arrival Preparations: In preparation for this Saturday’s OA-7 arrival, the crew deployed and performed a checkout of the Centerline Berthing Camera System (CBCS) on the Node 1 Nadir hatch. Video from the CBCS is used to aid Flight Controllers during Visiting Vehicle mating operations.

Urine Processing Assembly (UPA) Status: Overnight, the UPA experienced a fault due to apparent belt slippage in the DA. This signature has been seen on previous DAs, however it is the first occurrence since installing this ORU on April 13th. Ground teams are discussing the signature and forward plan for restarting the UPA.

Solar Array Wing (SAW) 3B Hinge Tear: During a review of imagery taken during Tuesday’s routine solar array inspection, ground teams identified a ~6-7 inch “tear” on one of the hinges of the 3B solar array blanket. The damage was reviewed prior to 50S docking and it was determined that, given the extent of the damage, there was no concern of propagation of that damage based on the expected loading conditions for the event. Followup imagery will be requested to assess the level of damage incurred and determine whether any additional actions will be required.

JAXA Protein Crystal Growth (PCG) #12 Installation and Execution:  The crew installed and configured the JAXA PCG#12 canisters in JEM Ryutai rack. This experiment will run until removal for return on 49S.  The two canisters contain a total of 47 protein samples that were prepared by Russian and Japanese researchers from universities, national research institutes, and the private sector. The purpose of this activity is to obtain high quality protein crystals in the microgravity environment at a constant temperature for about 6 weeks. Results may contribute to the development of drugs for multidrug-resistant bacteria, Alzheimer’s disease, muscular dystrophy and periodontitis. They will also aid in the development of a blood substitute and biosensor.

Orbital 7 (OA-7) Arrival Preparations: In preparation for OA-7 capture and berthing this Saturday, the crew completed the following:
•Reviewed Cygnus attached phase configuration, hardware, and stowage.
•Relocated Portable Computer System (PCS) and cables from Japanese Experiment Module Pressurized Module (JPM) Utility Outlet Panel (UOP) to the Lab UOP.
•Completed a Robotics Onboard Trainer (RoBOT) session to practice Capture Point hold runs and 2 meter runs.

RELEASE 17-046
NASA Astronaut Peggy Whitson Talks STEM Education with President Trump

Sets New U.S. Record for Time in Space

NASA astronaut Peggy Whitson, currently living and working aboard the International Space Station, broke the record Monday for cumulative time spent in space by a U.S. astronaut – an occasion that was celebrated with a phone call from President Donald Trump, First Daughter Ivanka Trump, and fellow astronaut Kate Rubins.

NASA astronaut Jack Fischer, who arrived April 20 for his first mission aboard the orbiting outpost, also participated in the call alongside Whitson.

"Peggy is a phenomenal role model for young women, and all Americans, who are exploring or participating in STEM education programs and careers," said President Trump. "As I have said many times before, only by enlisting the full potential of women in our society will we be truly able to make America great again. When I signed the INSPIRE Women Act in February, I did so to ensure more women have access to STEM education and careers, and to ensure America continues to benefit from the contributions of trailblazers like Peggy."

Whitson launched on Nov. 17, 2016, with 377 days in space already under her belt, and broke Jeff Williams’ U.S. record of 534 cumulative days in space. In 2008, Whitson became the first woman to command the space station, and on April 9 became the first woman to command it twice. In addition, she holds the record for most spacewalks by a female astronaut.

“This is an inspirational record Peggy is setting today, and she would be the first to tell you this is a record that’s absolutely made to be broken as we advance our knowledge and existence as both Americans and humans,” said NASA acting Administrator Robert Lightfoot. “The cutting-edge research and technology demonstrations on the International Space Station will help us go farther into our solar system and stay there longer, as we explore the mysteries of deep space first-hand. Congratulation to Peggy, and thank you for inspiring not only women, but all Americans to pursue STEM careers and become leaders.”

This is Whitson’s third long-duration stay on board the space station, and her mission was recently extended for an additional three months. Rather than returning to Earth in June as originally planned, Whitson will remain on the space station and her return home, with Fischer and Russian cosmonaut Fyodor Yurchikhin, is targeted for September. Whitson’s extension will give her significantly more time to conduct scientific experiments aboard the station.

A fresh set of science experiments and supplies for Whitson and her crewmates arrived at the space station April 22 on Orbital ATK’s seventh NASA-contracted commercial resupply mission. Investigations include an antibody investigation that could increase the effectiveness of chemotherapy drugs for cancer treatment and an advanced plant habitat for studying plant physiology and food growth in space. Another new investigation bound for the U.S. National Laboratory portion of the station will look at using magnetized cells and tools to make it easier to handle cells and cultures, and improve the reproducibility of experiments.

In addition to the important research that cannot be conducted on Earth, Fischer and Whitson are scheduled to take part in the fifth spacewalk of the year on May 12 to replace an avionics box on the starboard truss called an ExPRESS Logistics Carrier, a storage platform.

For more than 16 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth that will enable long-duration human and robotic exploration into deep space. A global endeavor, more than 200 people from 18 countries have visited the unique microgravity laboratory that has hosted more than 1,900 research investigations from researchers in more than 95 countries.

ISS Daily Summary Report – 4/24/2017

Posted on April 24, 2017 at 4:00 pm by HQ.
 

Orbital 7 (OA-7) Capture/Berthing: Friday night, Robotics Ground Controllers maneuvered the Space Station Remote Manipulator System (SSRMS) to inspect the Node 1 Nadir Active Common Berthing Mechanism (ABCM). They then maneuvered the SSRMS to the Cygnus high hover position and powered up the Mobile Servicing System (MSS) in “Hot Backup” mode in preparation for Saturday morning’s Cygnus capture.

On Saturday, Pesquet and Whitson monitored the Cygnus approach from the Cupola Robotic Workstation and with Pesquet at the controls, Cygnus was captured nominally. Ground Controllers then maneuvered Cygnus into position to support an inspection of its Passive Common Berthing Mechanism (CBM) then maneuvered and installed it to the Node 1 Nadir Active CBM. The Cygnus hatch was subsequently opened and cargo transfer was initiated.

Human Research Program (HRP) Collections (Marrow):  A 50S crewmember performed the Flight Day 15 (FD15) blood and air sample collections in support of the Marrow experiment.  A blood sample was collected, processed in the centrifuge and placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).  A breath sample and ambient air sample were also collected and stowed for return on a later flight. The Marrow investigation looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow.

NanoRacks Microscope-3 Instrument Operations:  The crew performed NanoRacks Microscope-3 assembly and checkout for both microscopes.  NanoRacks Microscope-3 will be used for viewing and capturing digital microscope photos of various science specimens.

Emergency Roles & Responsibilities Review: With the arrival of the 50S crew, all 5 crewmembers reviewed priorities during emergency response to ensure safety of the crew and safe configuration of the ISS. To meet these priorities the crew covered crew accountability, readiness of the Soyuz escape vehicle and communication and coordination among themselves as well as with ground teams during an emergency event.

Cycle Ergometer with Vibration Isolation and Stabilization (CEVIS) Status: On Sunday, the crew reported a grinding noise in the CEVIS and were directed to stand down on CEVIS use. Ground teams met and decided that the crew can continue CEVIS use wearing hearing protection and will schedule an Ergometer Remove & Replace (R&R).

Urine Processing Assembly (UPA) Status: On Sunday, UPA experienced a Distillation Assembly Belt Slippage Fault and was moded to shut down. The same fault was experienced last Thursday. Ground teams met and recommends restarting the UPA which is in work.

ISS Daily Summary Report – 4/25/2017

Posted on April 25, 2017 at 4:00 pm by HQ.

NanoRacks External Platform (NREP) Operations: The crew pressurized the Japanese Experiment Module Airlock (JEMAL), performed a leak check and extended the JEMAL Slide Table (ST) into the JEM Pressurized Module (JPM).  They then removed the Gumstix/Solar Cell payload and attached the NanoRacks-CID and Honeywell-Morehead-DM payloads to the NREP. The ST was then retracted with attached NREP back into the JEMAL and the hatch was closed. The JEMAL will be depressurized tomorrow and the JEMRMS will transfer the NREP to the JEM External Facility (JEM-EF) this Thursday.  NREP is the first external commercial research capability for testing of scientific investigations, sensors, and electronic components in space. Dependable Multiprocessor (DM) technology developed for NASA increases the amount of science and autonomy processing for space missions by flying clusters of high performance commercial off the shelf (COTS) processors in space.  Honeywell-Morehead-DM-7 includes a system-level radiation experiment to verify DM operation in a space environment.  Charge injection Devices (CIDs) read light exposure information in individual pixels.  The CID investigation evaluates a camera with image quality enhancements that can capture images of bright objects and extremely faint ones in the same field of view, such as stars and exoplanets. The investigation demonstrates that these cameras can work in the microgravity and high-radiation environment of space.

Fluid Shifts Baseline Imagery:  49S and 50S subjects began this week’s Fluid Shifts baseline imagery activities today.  With support from ground teams, the crew performed an Optical Coherence Tomography (OCT) test, a Distortion Product Otoacoustic Emission (DPOAE) test, a Tonometry examination, took blood pressure measurements, and performed an Ultrasound 2 scan.  This is the second of three weeks of Fluid Shifts activities for the 49S and 50S subjects.  Fluid Shifts is a joint NASA-Russian experiment divided into Dilution Measurements, Baseline Imaging, and Baseline Imaging with Chibis (Lower Body Negative Pressure). The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut’s eyes.  Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and to prevention of eye damage.

Dose Tracker: The crew completed a weekly medication tracking entry in the Dose Tracker application. Dose Tracker documents the medication usage of crewmembers before and during their missions by capturing data regarding medication use during spaceflight, including side effect qualities, frequencies and severities. The investigation is expected to provide anecdotal evidence of medication effectiveness during flight and any unusual side effects experienced. It is also expected that specific, near-real-time questioning about symptom relief and side effects will provide the data required to establish whether spaceflight-associated alterations in pharmacokinetics or pharmacodynamics is occurring during missions.

Radiation Dosimetry Inside ISS-Neutron (RaDI-N): After retrieving the RaDI-N hardware from the Russian crewmembers, the USOS crew deployed eight Space Bubble Detectors in Node 2 for the Radi-N2 experiment. The Canadian Space Agency’s RaDI-N investigation measures neutron radiation levels on the ISS. RaDI-N uses bubble detectors as neutron monitors which have been designed to detect neutrons while ignoring all other radiation.

Main Bus Switching Unit (MBSU) 2 Loss of Communications (LOC): Overnight, MBSU 2 experienced a LOC.  The ground is unable to command or get data insight into the MBSU. The unit continues to pass power to the downstream power buses 2A/2B DC-DC Converter Units (DDCU)s. The next worst failure is an MBSU 2 loss of power which would result in the downstream DDCUs losing power. Five of the 7 DDCUs have parallel DDCUs that can be used to manage and provide power to the loads. The other 2 standalone DDCUs can be powered using available contingency jumpers. The signature is similar to the previous MBSU 1 LOC failure requiring it to be replaced. There are two spare MBSUs on orbit. Teams met to discuss a recovery plan via Robotic operations or an EVA. 

Urine Processor Assembly (UPA) Status: The UPA was recovered yesterday, completing one process cycle.  There were some minor Distillation Assembly (DA) belt slippages at startup but not enough to result in a Low DA Centrifuge Speed (S4) shutdown. The next UPA process cycle is expected tomorrow.

ISS Daily Summary Report – 4/26/2017

Posted on April 26, 2017 at 4:00 pm by HQ.
 
NanoRacks External Platform (NREP) Operations:  The crew depressurized and vented the Japanese Experiment Module(JEM) Airlock (JEMAL) in preparation for the JEM Remote Manipulator System (JEMRMS) transfer of the NREP to the JEM External Facility (JEM-EF) this Friday. 

Fluid Shifts Baseline Imaging: The 49S crew continued this week’s Fluid Shifts baseline imagery activities.  With one crew member performing as an onboard operator, ultrasound imaging was taken of arterial and venous measures at various body locations. Additional measurements using the Cerebral and Cochlear Fluid Pressure (CCFP), Optical Coherence Tomography (OCT), ESA’s Cardiolab (CDL) Holter Arterial Blood Pressure Device, and Intraocular Pressure (IOP) were taken as well. Fluid Shifts is a joint NASA-Russian experiment that investigates the causes for severe and lasting physical changes to astronaut’s eyes. Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is investigated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and eye damage.

Electrostatic Levitation Furnace (ELF) Sample Holder Exchange: The crew completed a JAXA ELF Sample Chamber removal and inspection. The ELF is an experimental facility designed to levitate, melt and solidify materials by containerless processing techniques using the Electrostatic Levitation method. With this facility, thermophysical properties of high temperature melts can be measured, and solidification from deeply undercooled melts can be achieved.

Fine Motor Skills (FMS): The crew completed a series of interactive tasks for the FMS investigation which studies how fine motor skills are affected by long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth’s gravity. The goal of the investigation is to determine how fine motor performance in microgravity trends/varies over the duration of a six-month and year-long space mission; how fine motor performance on orbit compares with that of a closely matched participant on Earth; and how performance trends/varies before and after gravitational transitions including periods of early flight adaptation and very early/near immediate post-flight periods.

4K Ultra-High Definition (UHD) Streaming: The crew performed a successful 4K live video demo for the annual National Association of Broadcasters Convention (NAB). This meeting is attended by over 100,000 representatives in the media industry (ex., journalists, directors, producers and video engineers). The ISS showcased live 4K ISS downlink at a keynote address as part of the convention.

Mobile Servicing System (MSS) Operations:  Yesterday Robotics Ground Controllers powered off the Special Purpose Dexterous Manipulator (SPDM) and the Mobile Base System (MBS) and translated the Mobile Transporter (MT) from Worksite 6 (WS6) to WS3.  After powering the MBS and SPDM back up to operational they maneuvered the SPDM to unstow Robot Micro Conical Tool (RMCT) #2 from the Tool Holster Assembly (THA). This was the first day of operations to set up MSS for the Remote Power Control Module (RPCM) S11A-C swap with RPCM S14B-G scheduled this Friday, April 28th.

ISS Daily Summary Report – 4/25/2017

Posted on April 25, 2017 at 4:00 pm by HQ.

NanoRacks External Platform (NREP) Operations: The crew pressurized the Japanese Experiment Module Airlock (JEMAL), performed a leak check and extended the JEMAL Slide Table (ST) into the JEM Pressurized Module (JPM).  They then removed the Gumstix/Solar Cell payload and attached the NanoRacks-CID and Honeywell-Morehead-DM payloads to the NREP. The ST was then retracted with attached NREP back into the JEMAL and the hatch was closed. The JEMAL will be depressurized tomorrow and the JEMRMS will transfer the NREP to the JEM External Facility (JEM-EF) this Thursday.  NREP is the first external commercial research capability for testing of scientific investigations, sensors, and electronic components in space. Dependable Multiprocessor (DM) technology developed for NASA increases the amount of science and autonomy processing for space missions by flying clusters of high performance commercial off the shelf (COTS) processors in space.  Honeywell-Morehead-DM-7 includes a system-level radiation experiment to verify DM operation in a space environment.  Charge injection Devices (CIDs) read light exposure information in individual pixels.  The CID investigation evaluates a camera with image quality enhancements that can capture images of bright objects and extremely faint ones in the same field of view, such as stars and exoplanets. The investigation demonstrates that these cameras can work in the microgravity and high-radiation environment of space.
 

Bit confused here - when was NREP removed from the EF? Earlier in April?

JEM (Japanese Experiment Module) Airlock (JEMAL) Operations:  In preparation for the NanoRacks External Platform (NREP) activities planned for next week, the crew opened the inner hatch in the JEMAL and extended the airlock slide table into the JEM Pressurized Module (JPM).  They replaced the Multi-Purpose Experiment Platform (MPEP) on the Slide Table (ST) with the Cyclops to support the EVA contingency tie-down during NREP transfer to and from the ST via the JEM Remote Manipulator System (JEMRMS).  The crew then retracted the JEMAL slide table back into the airlock and closed the inner hatch. 
But there was no information in the stationreport, the same as with the installation of ExHAM#2 two weeks ago.
Maybe because it was done by JAXA and not by NASA.

THE SSRMS is removing/replacing something on the ISS feed.  An RPC?
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."
